Hi Maya,
I'm a very long waisted hourglass, so I'm always on the lookout for jeans with at least a 10" rise (which on me looks like a mid-rise). For reference, *all* the new Gap jeans (even the so-called higher waisted styles) and all of BR's jeans are much too short in the rise for me.
I also was on a quest for straight legs this fall I just got these Levis a couple of weeks ago, and so far I really like them, though I can't speak to their stretching out over time. They are a straight leg jean, and are about as close to a skinny jean as I am comfortable with on my hourglass body. They are high enough to contain the muffin top. They have quite a bit of stretch, but so far, at least, they seem to bounce back between wearings, if you know what I mean.

They have a 10.5" front rise, 14" back rise, 16" leg opening. I bought the Hammered Dark color. The price is right, and with Zappos return policy, I figured it was worth a try. I ordered both a 4 and 6 because I was kind of on the borderline, size wise, but the 4 turned out to be the best fit for me.
I hope that gives you another option. I have seen some Levis 512s at Kohls (the bootcut style, anyway), but not in the color or style I got.
